Abstract
Thermostatic gas valve with a pressure regulator The thermostatic gas valve (1) is adapted for delivering gas flows (7′,8′) to a main burner and to a pilot burner of a heater appliance and comprises a valve body (3) with a plurality of internal gas distribution chambers (4,5,5′) interconnected to a manual valve (11), to a main flow (7′) thermostatic modulating device (12), and to an electromagnetic safety valve (9) energised by a thermocouple (10), between a gas inlet duct (6) and outlet ducts (7,8) for said flows (7′,8′). An inlet pressure (Pe) regulator device (2) provided with a diaphragm type stabilising valve (18,19), is inserted in said inlet duct (6) in direct communication with the safety valve (9) via a flat conduit (27) under a valve body cover (14).
Claims5
A thermostatic gas valve adapted for delivering a main flow to a main burner and a pilot flow to a pilot burner of a heater appliance, comprising:
- a metal valve body with a plurality of internal gas distribution chambers, interconnected to a manual valve, to a thermostatic device for modulating the main flow, and to at least one electromagnetic safety valve energised by a thermocouple for detection of an ignition pilot flame;
- at least one gas inlet duct from a supply at a delivery pressure Pe, at least one main flow outlet duct connectable to the main burner, a pilot flow outlet duct connectable to the pilot burner, and
- a device for regulating the aforesaid pressure Pe delivered to the thermostatic valve, having a valve for stabilising said delivery pressure Pe;
- wherein the regulating device is configured as a cylindrical-shaped hollow metal body, installed from the outside in a housing in the thermostatic valve body, in direct connection with an inlet duct and in communication downstream with a safety valve in series with said inlet duct for stabilising the pilot flow gas pressure.
A thermostatic gas valve adapted for delivering a main flow to a main burner and a pilot flow to a pilot burner of a heater appliance, comprising:
- a metal valve body provided with a flat cover on at least one outer surface of the body, and a plurality of internal gas distribution chambers, interconnected to a manual valve, to a thermostatic device for modulating the main flow, and to at least one electromagnetic safety valve energised by a thermocouple for detection of the ignition pilot flame;
- at least one gas inlet duct from a supply at a delivery pressure Pe, at least one main flow outlet duct connectable to the main burner, and a pilot flow outlet duct connectable to the pilot burner;
- and
- a device for regulating said pressure Pe of the gas delivered to the thermostatic valve, having a valve for stabilising said delivery pressure Pe;
- wherein the regulating device is configured as a cylindrical-shaped hollow metal body, installed in direct connection with an inlet duct and in communication downstream with a safety valve via a flat conduit formed under said thermostatic valve body cover for stabilising the gas pressure of the pilot flow.
